in the present study, shearing properties of sugar cane stems were determined at five moisture content levels (46, 54, 62, 70 and 78% wb), three shearing speed (5, 10 and 15 mm min-1) and at ten positions on the stem. for measuring the shearing forces, the stems were severed by using a computer aided cutting apparatus. decrease in moisture content of stem from 78 to 46% wb led to 16.3 and 16.7%...

Three varieties of wheat and knife bevel angles, four levels of moisture content and three shearing speeds of pendulum were considered to determine their effects on the shearing energy of wheat straw. Results showed that the effects of variety, knife bevel angle, moisture content and shearing speed on shearing energy were significant (P<0.01). Shearing energy decreased with decreasing moisture ...

tomato is one of the sensitive fruits to mechanical impacts and physical tensions. the mostmechanical damages arise from handling which results in reducing tomato quality. in this study,impact energy effect has been studied in 3 different levels 0, 0.14 and 0.25 j by a pendulum impactapparatus, on changes of physicochemical properties of tomato, hybrid variety shiva f1, includingripening factor...

BACKGROUND The time required to harvest plant crops is important to the plant properties. It is affected by design of the harvest equipment and the desire for high-quality products with low energy usage. MATERIALS AND METHODS Strength characteristics of Origanum onites L., an important medicinal aromatic plant, harvested on 2, 9, 16 and 23 July, 2012-2014 (H1, H2, H3 and H4, respectively) wer...

We consider the nonaxisymmetric linear theory of radially-stratified disks. We work in a shearing-sheet-like approximation, where the vertical structure of the disk is neglected, and develop equations for the evolution of a plane-wave perturbation comoving with the shear flow (a shearing wave, or “shwave”). We calculate a complete solution set for compressive and incompressive short-wavelength ...

energy and mass transfer investigations in thermal processing of fruits serve as a breakthrough in the design and scale up of drying systems. diffusivity characteristics and specific energy consumption for drying of fig fruit in a laboratory scale microwave dryer were assessed. several intervals for microwave power intensity including 0.5, 1, 1.5, 2, and 2.5 w g-1, and 6 levels of power on-off ...

in this paper, non parametric data envelopment analysis (dea) was subjected to the energy data of wheat producers in punjab state, india, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. the main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...

We consider the adiabatic shearing of an incompressible non-Newtonian liquid with temperature dependent viscosity, subjected to steady shearing of the boundary. Identical equations govern the plastic shearing of a solid exhibiting thermal softening and strain rate sensitivity with constitutive relation obeying a certain power law. We establish that every classical solution approaches a uniform ...

the research was conducted in order to determine the bending stress, young’s modulus, shearing stress, and shearing energy of safflower stalk as a function of moisture content and stalk region. the bending forces were measured at different moisture contents and the bending stress and the young’s modulus were calculated from these data. for measuring the shear forces, the stalk specimens were se...
